The latest score has Hiarcs winning by >58.5 to 41.5. This still leaves Hiarcs in charge. It's possible also that 64 >Meg is too much memory for Hiarcs at Blitz but it's certainly much better than >4 Meg. I never thought I would see Fritz get beat at blitz like this. :-) >Jim Walker I believe that nothing is too much for Hiarcs because Hiarcs does not need time to clear the hash tables. In the worst case more hash tables do not help hiarcs but they are not counter productive. Fritz needs a small time to clear the hash tables every move and this is the reason that giving Fritz big hash tables may be counter productive in blitz. Uri
